A warm welcome to Contura.

A warm welcome to the Contura family. We hope

you will get a great deal of pleasure from your new

stove. As a new owner of a Contura stove you have

secured a product with timeless design and long

service life. Contura also has combustion that is both

environmentally friendly and eﬃcient for the best heat

production.

Read through these installation instructions carefully

before installation. Read how to best light your stove in

the lighting instructions.

NOTE!

Report the installation of a stove to

your local authority.

The owner of the house is personally responsible

for ensuring compliance with the mandatory safety

requirements and must have the installation approved by

a qualified inspector. Your local chimney sweep must also

be informed about the installation as this will affect the

routines for regular chimney-sweeping services.

WARNING!

The stove becomes very hot.

During operation, certain surfaces of the stove become

very hot and can cause burn injury if touched. Be aware

of the strong heat radiated through the hatch glass.

Placing flammable material closer than the safe distance

indicated may cause a fire. Smouldering can cause quick

gas ignition with the risk of damage to property and

personal injury.

FACTS

Building application

Before installing a stove or erecting a

chimney it is necessary for you to apply

for planning permission from your local

authority. Ask your local authority for

advice regarding building regulations and

the application.

Chimney

Note! The stove installation and connection

to a chimney must be accomplished with

the current edition of Building Regulations.

We recommend that you consult a local

chimney sweep before the installation

to make sure that the chimney is in good

condition.

The stove is type approved and must be

connected to a chimney dimensioned

for at least 350°C. The connector on

the appliance is suitable for pipes with

diameter of 125 mm.

A flexible flue liner or steel flue

certified for use with solid fuel is highly

recommended. The stove requires a

draught in the chimney of at least –12

Pa. The draught is affected both by the

length and area of the chimney, and by how

well sealed it is. Minimum recommended

chimney length is 3.5 m and a suitable

cross section area is 120-175 cm² (125-

150 mm in diameter). Carefully check that

the chimney is sealed and that there is

no leakage around soot hatches and flue

connections.

Note that a flue with sharp bends and

horizontal routing reduces the draught in

the chimney. Maximum horizontal flue is 1

m, on the condition that the vertical flue

length is at least 5 m. It must be possible

to sweep the full length of the flue and the

soot hatches must be easily accessible.

General

In this manual you will find instructions

about how your Contura i4 shall be

installed. Before you start the installation

it is important that you read this

instruction carefully and fully understand

the requirements. All European, national

and local standards and regulations needs

to be fulfilled when the appliance are

installed.

To guarantee the function and safety of

the stove we recommend that it is installed

by a professional. Our Contura agents can

recommend a suitable installer.

The room or space containing a stove shall

have a permanent air supply sufficent to

ensure proper combustion, to determine

correct amount of air supply use current

edition of Building Regulations.

Remember to use only for the appliance

recommended fuel as wood logs

or smokeless fuel as anthracite or

manufactured smokeless fuel briquettes.

Do not ever burn bituminous coal, “petro-

coke” or other petroleum based fuels!

When recessing the insert, adjacent walls that are not classed as fire walls or are considered unsuitable for heat loads must be protected

by non-combustible material according to the specification below.

All joints on the non-combustible material must be sealed using the manufacture’s recommended method. The area between the insert

and the recess must be ventilated according to the specification/dimension.

When top connecting a steel flue please refer to the relevant manufacturer’s installation instructions. Observe the safety distances to

combustible material that steel flues require. Heat radiation from the hatch is strong and is why combustible material must not be placed

closer than 1 m in front of the hatch. When recessing, building material must not be in direct contact with the insert due to the thermal

expansion of the insert.

Material requirements

The building material must not be combustible.

The thermal conductivity coefficient

λ may be a maximum of 0.14 W/mK.

The thickness of the building material must always be at least 100 mm.

In cases where the building material’s insulation properties are given as a U-Value, this must be a maximum of 1.4 W/ m²K.

List of suitable materials:

Aerated concrete:

λ =0.12-0.14

Vermiculite:

λ =0.12-0.14

Calcium silicate: λ =0,09

Recessing the insert

Heat shield

If the recess is to extend to the ceiling, a heat shield must be made above the convection exhaust. This is to prevent hot air collecting in

the recess closest to the ceiling. The seal must a maximum of 100 mm above the convection exhaust’s upper edge and must be made up

of 20 mm thick building boards made of calcium silicate or a panel with at least a 50 mm thickness of rock wool on top.

Convection air

The convection air ventilates the surround, cools the insert and transports the hot air out into the room. The total sum of the effective

cross section area up and down must not be less than the stated values. The air intake must be positioned somewhere between the floor

and the bottom of the insert, up to or on the sides of the recess. The vent must be positioned above the insert’s highest point up to or to

the sides of the recess.

Observe the minimum distance up to the ceiling.

Convection air in: 200 cm²

Convection air out: 200 cm²

Note that building regulations apply regarding the area below and in front of the insert, see section ”Hearth plate” below.

Load bearing base

Ensure that the bottom of the convection box is installed on a loadbearing with the strength to support the weight of the insert and the

chimney. The insert can be loaded maximum 100 kg of chimney. The load bearing must not prevent the convection air ventilate the area

between the insert and recsess.

Hearth plate

Due to the risk of falling embers, a flammable floor must be protected by a hearth plate. It must extend 300 mm in front of the stove

and 100 mm on each side of the stove, or have a 200 mm extension on each side of the opening. The hearth plate can consist of natural

stone, concrete, metal plate or glass, consult the Building regulations.

Installation in Builders opening

Supply of combustion air

When a stove is installed in a room, the demand for air supply to

the room increases. Air can be provided indirectly via a vent in the

outer wall or via a duct from the outside that is connected to the

stove. The amount of air needed for combustion is approximatly

20m³/h.

If the insert will be used with supply air connector (accessory)

and outside air-supply kit (accessory) then prepare the convection

box by open the lid where the air supply hose will enter, from side

or back. Make the supply air connector installation as the flue pipe

is connected to the convection box.
